Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Aerogel Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 catalysts for hydrodesulphurisation of dibenzothiophene and 4,6-dimethyldibenzothiophene
(Catalysis Today, 2021)
Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 aerogel catalysts were synthesized using sol-gel method and super-critical drying in excess solvent, and investigated in the hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and ...
A Strategy to Revalue a Wood Waste for Simultaneous Cadmium Removal and Wastewater Disinfection
(Adsorption Science & Technology, 2021)
In this investigation, the possibility of wood waste (hardwoods such as oaks' and alternatives' staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All ...
Inhibitory Effect of Cerium Salts of Lower Carboxylic Acids on Al-Zn-Mg-Cu Alloy in NaCl Solution
(Journal of the Electrochemical Society, 2021)
The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition ...
Structure and Strength of Isothermally Heat-Treated Medium Carbon Ti-V Microalloyed Steel
(Metals, 2021)
Isothermal transformation characteristics of a medium carbon Ti-V microalloyed steel were investigated using light microscopy, scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), and by ...
Experimental and numerical research on the failure of railway vehicles coupling links
(Engineering Failure Analysis, 2021)
Two modes of failure are analysed for coupling links, the mechanical connections that transmit traction forces between vehicles along the length of a train. Coupling links are designed to withstand the dynamic loads in ...
